Not sure why this got downvoted, I was having the exact same problem the other day. The problem may be that, like me, you're expecting to see a message from Facebook (via notifications) about this. That's not how it works. You will get a developer request, which will show up on your requests panel--this thing, which appears in the right-hand column:

At the bottom it should say "1 developer request". Click through to that and approve the app, and you should be good to go.
